An iron Tyre of diameter 50cm at 288k is to be shrank on to a wheel of diameter 50.35cm. To what temperature must the tyre be heated so that it will slip over the wheel with a radial gap of 0.5mm. Linear expansivity of iron is 0.000012k-1 ​

Your pendulum clock which advances 1.0 s for every complete oscillation of the pendulum is running perfectly on earth at a site where the magnitude of the acceleration due to gravity is 9.80 m/s2. you send the clock to a location on the moon where the magnitude of the acceleration due to gravity is 1.65 m/s2.

The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.

What is the moment of inertia i of this assembly about the axis through which it is pivoted? express the moment of inertia in terms of mr
